    BROWN, Circuit Judge: Ali Mohamed Ali, a Somali
    national, helped negotiate the ransom of a merchant vessel
    and its crew after they were captured by marauders in the
    Gulf of Aden. Though he claims merely to have defused a
    tense situation, the government believes he was in cahoots
    with these brigands from the very start. Ali eventually made
    his way to the United States, where he was arrested and
    indicted for conspiring to commit and aiding and abetting two
    offenses: piracy on the high seas and hostage taking.
    The government says Ali is a pirate; he protests that he is
    not. Though a trial will determine whether he is in fact a
    pirate, the question before us is whether the government’s
    allegations are legally sufficient. And the answer to that
    question is complicated by a factor the district court deemed
    critical: Ali’s alleged involvement was limited to acts he
    committed on land and in territorial waters—not upon the
    high seas. Thus, the district court restricted the charge of
    aiding and abetting piracy to his conduct on the high seas and
    dismissed the charge of conspiracy to commit piracy.
    Eventually, the district court also dismissed the hostage taking
    charges, concluding that prosecuting him for his acts abroad
    would violate his right to due process. On appeal, we affirm
    dismissal of the charge of conspiracy to commit piracy. We
    reverse, however, the district court’s dismissal of the hostage
    taking charges, as well as its decision to limit the aiding and
    abetting piracy charge.
    I. BACKGROUND
    A. Modern Piracy
    Mention “pirates” to most Americans and you are more
    likely to evoke Johnny Depp’s droll depiction of Captain Jack
    Sparrow than concern about the international scourge of
    3
    piracy that long ago led most civilized states to declare such
    marauders the enemy of all mankind. In unstable parts of the
    world, piracy is serious business, and these troubled waters
    have seen a resurgence in pirate attacks, both successful and
    attempted. See, e.g., INT’L MAR. ORG., MSC.4/ CIRC.180,
    REPORTS ON ACTS OF PIRACY AND ARMED ROBBERY AGAINST
    SHIPS: ANNUAL REPORT – 2011, at 2 (2012); INT’L MAR.
    ORG., MSC.4/CIRC.169, REPORTS ON ACTS OF PIRACY AND
    ARMED ROBBERY AGAINST SHIPS: ANNUAL REPORT – 2010, at
    2 (2011). Pirate attacks have become increasingly daring, as
    well as commonplace, with pirates targeting large commercial
    vessels in transit, hijacking these ships, and ransoming the
    crews. See W. Michael Reisman & Bradley T. Tennis,
    Combating Piracy in East Africa, 35 YALE J. INT’L. L.
    ONLINE 14, 16–18 (2009). These predatory activities have
    proven especially lucrative in the Gulf of Aden (situated
    between the Arabian Peninsula and the Horn of Africa and
    bounded by a long stretch of Somalia’s coast), where pirates
    can exploit a key trade route undeterred by Somalia’s unstable
    government. See Milena Sterio, The Somali Piracy Problem:
    A Global Puzzle Necessitating A Global Solution, 59 AM. U.
    L. REV. 1449, 1450–51 (2010).
    B. Ali’s Offense and Prosecution 1
    Ali is a member of Somalia’s Warsengeli clan, 2 which,
    together with the Majertein clan, plotted the capture of the
    1
    The facts are undisputed for the purpose of this appeal, which
    concerns only the legal sufficiency of the government’s case. See
    United States v. Lattimore, 
    215 F.2d 847
    , 849, 851 (D.C. Cir.
    1954).
    2
    According to a previous government filing, Ali’s origins are
    not entirely certain, since he has represented himself on prior
    occasions sometimes as a Somali national and at other times as a
    4
    CEC Future, a Danish-owned merchant ship that flew a
    Bahamian flag and carried cargo owned by a U.S.
    corporation. On November 7, 2008, while the CEC Future
    was traveling in the Gulf of Aden on the “high seas”—i.e.,
    outside any nation’s territorial waters, RESTATEMENT (THIRD)
    OF FOREIGN RELATIONS LAW § 521 cmt. a (1987)—Ali’s
    compatriots launched their attack. Wielding AK-47s and a
    rocket-propelled grenade, the raiders fired warning shots,
    boarded the ship, and seized the crew. They then forced
    crewmembers at gunpoint to reroute the ship to Point Ras
    Binna, off the coast of Somalia, where, on November 9, Ali
    came aboard and assumed the role of interpreter. The ship
    traveled that same day to Eyl, a Somali port, and remained at
    anchor there until it was ransomed the following January.
    Except for a brief period of “minutes” during which the
    CEC Future entered the high seas, the ship traversed
    exclusively territorial waters while Ali was aboard. Ali
    promptly began negotiating with the owners of the CEC
    Future, starting with an initial demand of $7 million for the
    release of the ship, its crew, and its cargo. Discussions
    continued into January 2009, when Ali and the CEC Future’s
    owners agreed to a $1.7 million ransom. As payment for his
    assistance, Ali also demanded $100,000 (a figure he later
    reduced to $75,000) be placed in a personal bank account. On
    January 14, the pirates received the agreed-upon $1.7 million,
    and two days later Ali and his cohorts left the ship. Ali’s share
    amounted to $16,500—one percent of the total ransom less
    expenses. He later received his separate $75,000 payment via
    wire transfer to the account he had previously specified.

    As it happens, “pirate hostage negotiator” is not the only
    line on Ali’s resume. In June 2010, he was appointed Director
    General of the Ministry of Education for the Republic of
    Somaliland, a self-proclaimed sovereign state within Somalia.
    United States v. Ali (“Ali I”), 
    870 F. Supp. 2d 10
    , 17 (D.D.C.
    2012). When he received an email in March 2011 inviting
    him to attend an education conference in Raleigh, North
    Carolina, he agreed. 
    Id.
     Little did he know it was all an
    elaborate ruse. For some time, federal prosecutors had been
    busy building a case against Ali, charging him via criminal
    complaint and later obtaining a formal indictment. When Ali
    landed at Dulles International Airport on April 20, 2011, to
    attend the sham conference, he was promptly arrested. 
    Id.
    A grand jury issued a four-count superseding indictment
    against Ali, charging him first with conspiracy to commit
    piracy under the law of nations, in violation of 
    18 U.S.C. § 371
    , which makes it a crime for “two or more persons” to
    “conspire . . . to commit any offense against the United
    States.” Invoking aiding and abetting liability under 
    18 U.S.C. § 2
    , Count Two charged Ali with committing piracy under the
    law of nations, in violation of 
    18 U.S.C. § 1651
    , which
    provides, “Whoever, on the high seas, commits the crime of
    piracy as defined by the law of nations, and is afterwards
    brought into or found in the United States, shall be
    imprisoned for life.” Counts Three and Four analogously
    charged Ali with conspiracy to commit hostage taking and
    aiding and abetting hostage taking, in violation of 
    18 U.S.C. §§ 1203
     and 2. The hostage taking statute prescribes criminal
    penalties for
    whoever, whether inside or outside the United
    States, seizes or detains and threatens to kill, to
    injure, or to continue to detain another person
    in order to compel a third person or a
    6
    governmental organization to do or abstain
    from doing any act as an explicit or implicit
    condition for the release of the person
    detained, or attempts or conspires to do so.
    
    Id.
     § 1203(a).
    Ali filed a motion to dismiss the charges as legally
    defective, meeting with partial success. See United States v.
    Ali (“Ali II”), 
    885 F. Supp. 2d 17
    , 45–46 (D.D.C. 2012).
    Beginning with the premise that the definition of piracy under
    international law does not encompass conspiratorial liability,
    the district court dismissed Count One in full, concluding
    § 1651, which defines piracy in terms of “the law of nations,”
    could not ground a conspiracy charge. See id. at 33. The court
    similarly refused to interpret § 371, the federal conspiracy
    statute, as applying to piracy under the law of nations. So
    read, the court said, the statute would contravene international
    law in a way Congress never intended. See id. at 33–34. As
    for Count Two, the court reasoned piracy under § 1651 and
    international law only concerns acts committed on the high
    seas and consequently limited Count Two to acts of aiding
    and abetting Ali committed while he was on the high seas. See
    id. at 32. Finally, the district court declined to dismiss Counts
    Three and Four, ruling that Congress intended whatever
    conflict exists between international law and extraterritorial
    application of § 1203, id. at 35, and that prosecution for
    extraterritorial acts of hostage taking satisfied the notice
    requirements of due process because Ali’s piracy offenses
    already subjected him to the universal jurisdiction of the
    United States, id. at 44–45.
    The district court reconsidered Counts Three and Four,
    however, after learning that the government had no “specific
    evidence” Ali had facilitated any acts of piracy while outside
    7
    territorial waters, and that the CEC Future proceeded on the
    high seas only for a matter of minutes while Ali was aboard.
    See United States v. Ali (“Ali III”), 
    885 F. Supp. 2d 55
    , 58
    (D.D.C. 2012). Due process, the court said, is satisfied only if
    Ali had some reasonable expectation he could be haled into an
    American court. So long as the government could establish
    that he had committed piracy on the high seas—a crime over
    which all nations may exercise jurisdiction—this expectation
    was met. But because Ali’s criminal conduct took place in
    territorial waters, he had no notice his actions subjected him
    to prosecution in the United States for hostage taking. Thus,
    in light of the government’s revelation that it could not show
    Ali’s offenses occurred on the high seas, due process
    precluded exercising jurisdiction over Counts Three and Four.
    
    Id. at 62
    .
    The government now challenges the district court’s
    dismissal of Counts One, Three, and Four, as well as
    limitation of Count Two. We have jurisdiction over this
    interlocutory appeal because the government challenges an
    “order of a district court dismissing an indictment . . . as to
    any one or more counts.” 
    18 U.S.C. § 3731
    .
    II. THE PIRACY CHARGES
    In most cases, the criminal law of the United States does
    not reach crimes committed by foreign nationals in foreign
    locations against foreign interests. Two judicial presumptions
    promote this outcome. The first is the presumption against the
    extraterritorial effect of statutes: “When a statute gives no
    clear indication of an extraterritorial application, it has none.”
    Morrison v. Nat’l Austl. Bank Ltd., 
    130 S. Ct. 2869
    , 2878
    (2010). The second is the judicial presumption that “an act of
    Congress ought never to be construed to violate the law of
    nations if any other possible construction remains,” Murray v.
    8
    Schooner Charming Betsy, 6 U.S. (2 Cranch) 64, 118
    (1804)—the so-called Charming Betsy canon. Because
    international law itself limits a state’s authority to apply its
    laws beyond its borders, see RESTATEMENT (THIRD) OF
    FOREIGN RELATIONS LAW §§ 402–03, Charming Betsy
    operates alongside the presumption against extraterritorial
    effect to check the exercise of U.S. criminal jurisdiction.
    Neither presumption imposes a substantive limit on
    Congress’s legislative authority, but they do constrain judicial
    inquiry into a statute’s scope.
    Piracy, however, is no ordinary offense. The federal
    piracy statute clearly applies extraterritorially to “[w]hoever,
    on the high seas, commits the crime of piracy as defined by
    the law of nations,” even though that person is only
    “afterwards brought into or found in the United States.” 
    18 U.S.C. § 1651
    . Likewise, through the principle of universal
    jurisdiction, international law permits states to “define and
    prescribe punishment for certain offenses recognized by the
    community of nations as of universal concern.”
    RESTATEMENT (THIRD) OF FOREIGN RELATIONS LAW § 404;
    see United States v. Yunis, 
    924 F.2d 1086
    , 1091 (D.C. Cir.
    1991). And of all such universal crimes, piracy is the oldest
    and most widely acknowledged. See, e.g., Kenneth C.
    Randall, Universal Jurisdiction Under International Law, 66
    TEX. L. REV. 785, 791 (1988). “Because he commits
    hostilities upon the subjects and property of any or all nations,
    without any regard to right or duty, or any pretence of public
    authority,” the pirate is “hostis humani generis,” United States
    v. Brig Malek Adhel, 43 U.S. (2 How.) 210, 232 (1844)—in
    other words, “an enemy of the human race,” United States v.
    Smith, 18 (5 Wheat.) U.S. 153, 161 (1820). Thus, “all nations
    [may punish] all persons, whether natives or foreigners, who
    have committed this offence against any persons whatsoever,
    with whom they are in amity.” Id. at 162.
    9
    Universal jurisdiction is not some idiosyncratic domestic
    invention but a creature of international law. Unlike the
    average criminal, a pirate may easily find himself before an
    American court despite committing his offense on the other
    side of the globe. Ali’s situation is a bit more complicated,
    though. His indictment contains no straightforward charge of
    piracy. Rather, the government accuses him of two inchoate
    offenses relating to piracy: conspiracy to commit piracy and
    aiding and abetting piracy.
    On their face, both ancillary statutes apply generally and
    without exception: § 2 to “[w]hoever . . . aids, abets, counsels,
    commands, induces or procures” the commission of “an
    offense against the United States,” 
    18 U.S.C. § 2
    (a) (emphasis
    added), and § 371 to persons who “do any act to effect the
    object of the conspiracy” to “commit any offense against the
    United States,” 
    18 U.S.C. § 371
     (emphasis added). But so
    powerful is the presumption against extraterritorial effect that
    even such generic language is insufficient rebuttal. See Small
    v. United States, 
    544 U.S. 388
     (2005). That leaves both
    statutes ambiguous as to their application abroad, requiring us
    to resort to interpretive canons to guide our analysis.
    Given this ambiguity in the extraterritorial scope of the
    two ancillary statutes, we consider whether applying them to
    Ali’s actions is consistent with international law. Conducting
    this Charming Betsy analysis requires parsing through
    international treaties, employing interpretive canons, and
    delving into drafting history. Likewise, because the two
    ancillary statutes are “not so broad as to expand the
    extraterritorial reach of the underlying statute,” United States
    v. Yakou, 
    428 F.3d 241
    , 252 (D.C. Cir. 2005), we also
    conduct a separate analysis to determine the precise contours
    of § 1651’s extraterritorial scope. Ultimately, Ali’s assault on
    10
    his conspiracy charge prevails for the same reason the attack
    on the aiding and abetting charge fails.
    A. Aiding and Abetting Piracy
    We begin with Ali’s charge of aiding and abetting piracy.
    Aiding and abetting is a theory of criminal liability, not a
    separate offense, United States v. Ginyard, 
    511 F.3d 203
    , 211
    (D.C. Cir. 2008)—one that allows a defendant who “aids,
    abets, counsels, commands, induces or procures” commission
    of a crime to be punished as a principal, 
    18 U.S.C. § 2
    (a). “All
    that is necessary is to show some affirmative participation
    which at least encourages the principal offender to commit the
    offense, with all its elements, as proscribed by the statute.”
    United States v. Raper, 
    676 F.2d 841
    , 850 (D.C. Cir. 1982).
    From Ali’s perspective, it is not enough that acts of piracy
    were committed on the high seas and that he aided and
    abetted them. Rather, he believes any acts of aiding and
    abetting he committed must themselves have occurred in
    extraterritorial waters and not merely supported the capture of
    the CEC Future on the high seas.
    Ali’s argument involves two distinct (though closely
    related) inquiries. First, does the Charming Betsy canon pose
    any obstacle to prosecuting Ali for aiding and abetting piracy?
    For we assume, absent contrary indication, Congress intends
    its enactments to comport with international law. Second, is
    the presumption against extraterritoriality applicable to acts of
    aiding and abetting piracy not committed on the high seas?
    1. Piracy and the Charming Betsy Canon
    Section 1651 criminalizes “the crime of piracy as defined
    by the law of nations.” Correspondence between the domestic
    and international definitions is essential to exercising
    11
    universal jurisdiction. Otherwise, invocation of the magic
    word “piracy” would confer universal jurisdiction on a nation
    and vest its actions with the authority of international law. See
    Randall, supra, at 795. As a domestic matter, doing so may be
    perfectly legal. But because Charming Betsy counsels against
    interpreting federal statutes to contravene international law,
    we must satisfy ourselves that prosecuting Ali for aiding and
    abetting piracy would be consistent with the law of nations.
    Though § 1651’s invocation of universal jurisdiction may
    comport with international law, that does not tell us whether
    § 2’s broad aider and abettor liability covers conduct neither
    within U.S. territory nor on the high seas. Resolving that
    difficult question requires examining precisely what conduct
    constitutes piracy under the law of nations. Luckily, defining
    piracy is a fairly straightforward exercise. Despite not being a
    signatory, the United States has recognized, via United
    Nations Security Council resolution, that the U.N. Convention
    on the Law of the Sea (“UNCLOS”) “sets out the legal
    framework applicable to combating piracy and armed robbery
    at sea.” S.C. Res. 2020, U.N. Doc. S/Res/2020, at 2 (Nov. 22,
    2011); see United States v. Dire, 
    680 F.3d 446
    , 469 (4th Cir.
    2012). According to UNCLOS:
    Piracy consists of any of the following acts:
    (a)    any illegal acts of violence or detention,
    or any act of depredation, committed for
    private ends by the crew or the
    passengers of a private ship . . . and
    directed:
    (i) on the high seas, against another
    ship . . . or against persons or
    property on board such ship . . . ;
    12
    (ii) against a ship, . . . persons or
    property in a place outside the
    jurisdiction of any State;
    (b)   any act of voluntary participation in the
    operation of a ship . . . with knowledge
    of facts making it a pirate ship . . . ;
    (c)   any act of inciting or of intentionally
    facilitating an act described in
    subparagraph (a) or (b).
    UNCLOS, art. 101, Dec. 10, 1982, 1833 U.N.T.S. 397, 436.
    By including “intentionally facilitating” a piratical act within
    its definition of piracy, article 101(c) puts to rest any worry
    that American notions of aider and abettor liability might fail
    to respect the international understanding of piracy. 3 One
    question remains: does international law require facilitative
    acts take place on the high seas?
    Explicit geographical limits—“on the high seas” and
    “outside the jurisdiction of any state”—govern piratical acts
    under article 101(a)(i) and (ii). Such language is absent,
    however, in article 101(c), strongly suggesting a facilitative
    act need not occur on the high seas so long as its predicate
    offense has. Cf. Dean v. United States, 
    556 U.S. 568
    , 573
    (2009) (“[W]here Congress includes particular language in
    one section of a statute but omits it in another section of the
    same Act, it is generally presumed that Congress acts
    intentionally and purposely in the disparate inclusion or
    exclusion.” (internal quotation marks omitted)). So far, so
    good; Charming Betsy poses no problems.
    3
    As neither party draws support for its position from article
    101(b), we need not opine on its meaning here.
    13
    Ali endeavors nonetheless to impute a “high seas”
    requirement to article 101(c) by pointing to UNCLOS article
    86, which states, “The provisions of this Part apply to all parts
    of the sea that are not included in the exclusive economic
    zone, in the territorial sea or in the internal waters of a State,
    or in the archipelagic waters of an archipelagic State.” 1833
    U.N.T.S. at 432. Though, at first glance, the language at issue
    appears generally applicable, there are several problems with
    Ali’s theory that article 86 imposes a strict high seas
    requirement on all provisions in Part VII. For one thing, Ali’s
    reading would result in numerous redundancies throughout
    UNCLOS where, as in article 101(a)(i), the term “high seas”
    is already used, and interpretations resulting in textual
    surplusage are typically disfavored. Cf. Babbitt v. Sweet
    Home Chapter of Communities for a Great Or., 
    515 U.S. 687
    ,
    698 (1995). Similarly, many of the provisions to which article
    86 applies explicitly concern conduct outside the high seas.
    See, e.g., UNCLOS, art. 92(1), 1833 U.N.T.S. at 433 (“A ship
    may not change its flag during a voyage or while in a port of
    call . . . .”); 
    id.
     art. 100, 1833 U.N.T.S. at 436 (“All States
    shall cooperate to the fullest possible extent in the repression
    of piracy on the high seas or in any other place outside the
    jurisdiction of any State.”). Ali’s expansive interpretation of
    article 86 is simply not plausible.
    What does article 86 mean, then, if it imposes no high
    seas requirement on the other articles in Part VII of
    UNCLOS? After all, “the canon against surplusage merely
    favors that interpretation which avoids surplusage,” not the
    construction substituting one instance of superfluous language
    for another. Freeman v. Quicken Loans, Inc., 
    132 S. Ct. 2034
    ,
    2043 (2012). We believe it is best understood as definitional,
    explicating the term “high seas” for that portion of the treaty
    most directly discussing such issues. Under this interpretation,
    article 86 mirrors other prefatory provisions in UNCLOS. Part
    14
    II, for example, concerns “Territorial Sea and Contiguous
    Zone” and so opens with article 2’s explanation of the legal
    status of a State’s territorial sea. 1833 U.N.T.S. at 400. And
    Part III, covering “Straits Used for International Navigation,”
    begins with article 34’s clarification of the legal status of
    straits used for international navigation. 1833 U.N.T.S. at 410.
    Drawing guidance from these provisions, article 86 makes the
    most sense as an introduction to Part VII, which is titled
    “High Seas,” and not as a limit on jurisdictional scope. Cf.
    FDA v. Brown & Williamson Tobacco Corp., 
    529 U.S. 120
    ,
    133 (2000) (“It is a fundamental canon of statutory
    construction that the words of a statute must be read in their
    context and with a view to their place in the overall statutory
    scheme.” (internal quotation marks omitted)).
    Thwarted by article 101’s text, Ali contends that even if
    facilitative acts count as piracy, a nation’s universal
    jurisdiction over piracy offenses is limited to high seas
    conduct. In support of this claim, Ali invokes UNCLOS
    article 105, which reads,
    On the high seas, or in any other place outside
    the jurisdiction of any State, every State may
    seize a pirate ship or aircraft, or a ship or
    aircraft taken by piracy and under the control
    of pirates and arrest the persons and seize the
    property on board. The courts of the State
    which carried out the seizure may decide upon
    the penalties to be imposed . . . .
    1833 U.N.T.S. at 437. Ali understands article 105’s preface to
    govern the actual enforcement of antipiracy law—and, by
    extension, to restrict universal jurisdiction to the high seas—
    even if the definition of piracy is more expansive. In fact, Ali
    gets it backward. Rather than curtailing the categories of
    15
    persons who may be prosecuted as pirates, the provision’s
    reference to the high seas highlights the broad authority of
    nations to apprehend pirates even in international waters. His
    reading also proves too much, leaving nations incapable of
    prosecuting even those undisputed pirates they discover
    within their own borders—a far cry from “universal”
    jurisdiction. Article 105 is therefore no indication
    international law limits the liability of aiders and abettors to
    their conduct on the high seas.
    Ali’s next effort to exclude his conduct from the
    international definition of piracy eschews UNCLOS’s text in
    favor of its drafting history—or, rather, its drafting history’s
    drafting history. He points to UNCLOS’s origins in article 15
    of the 1958 Geneva Convention on the High Seas, which
    closely parallels the later treaty’s article 101. See Geneva
    Convention on the High Seas, art. 15, Apr. 29, 1958, 13
    U.S.T. 2312, 450 U.N.T.S. 82. Article 15 was based in large
    part on a model convention compiled at Harvard Law School
    by various legal scholars, see 2 ILC YEARBOOK 282 (1956),
    who postulated that “[t]he act of instigation or facilitation is
    not subjected to the common jurisdiction unless it takes place
    outside territorial jurisdiction.” Joseph W. Bingham et al.,
    Codification of International Law: Part IV: Piracy, 26 AM. J.
    INT’L L. SUPP. 739, 822 (1932). Ali hopes this latter statement
    is dispositive.
    Effectively, Ali would have us ignore UNCLOS’s plain
    meaning in favor of eighty-year-old scholarship that may have
    influenced a treaty that includes language similar to UNCLOS
    article 101. This is a bridge too far. Legislative history is an
    imperfect enough guide when dealing with acts of Congress.
    See Conroy v. Aniskoff, 
    507 U.S. 511
    , 519 (1993) (Scalia, J.,
    concurring in the judgment) (“If one were to search for an
    interpretive technique that, on the whole, was more likely to
    16
    confuse than to clarify, one could hardly find a more
    promising candidate than legislative history.”). Ali’s
    inferential chain compounds the flaws—and that even
    assumes a single intent can be divined as easily from the
    myriad foreign governments that ratified the agreement as
    from a group of individual legislators. Even were it a more
    feasible exercise, weighing the relevance of scholarly work
    that indirectly inspired UNCLOS is not an avenue open to us.
    Basic principles of treaty interpretation—both domestic and
    international—direct courts to construe treaties based on their
    text before resorting to extraneous materials. See United
    States v. Alvarez-Machain, 
    504 U.S. 655
    , 663 (1992) (“In
    construing a treaty, as in construing a statute, we first look to
    its terms to determine its meaning.”); Vienna Convention on
    the Law of Treaties, art. 32, May 23, 1969, 8 I.L.M. 679, 692,
    1155 U.N.T.S. 331, 340. Because international law permits
    prosecuting acts of aiding and abetting piracy committed
    while not on the high seas, the Charming Betsy canon is no
    constraint on the scope of Count Two.
    2. Piracy and the Presumption Against Extraterritorial Effect
    Ali next attempts to achieve through the presumption
    against extraterritoriality what he cannot with Charming
    Betsy. Generally, the extraterritorial reach of an ancillary
    offense like aiding and abetting or conspiracy is coterminous
    with that of the underlying criminal statute. Yakou, 
    428 F.3d at 252
    . And when the underlying criminal statute’s
    extraterritorial reach is unquestionable, the presumption is
    rebutted with equal force for aiding and abetting. See United
    States v. Hill, 
    279 F.3d 731
    , 739 (9th Cir. 2002) (“[A]iding
    and abetting[] and conspiracy . . . have been deemed to confer
    extraterritorial jurisdiction to the same extent as the offenses
    that underlie them.”); see also Yunis, 
    924 F.2d at 1091
    (analyzing underlying offenses under extraterritoriality canon
    17
    but conducting no separate analysis with respect to conspiracy
    conviction). Ali admits the piracy statute must have some
    extraterritorial reach—after all, its very terms cover conduct
    outside U.S. territory—but denies that the extraterritorial
    scope extends to any conduct that was not itself perpetrated
    on the high seas.
    We note, as an initial matter, that proving a defendant
    guilty of aiding and abetting does not ordinarily require the
    government to establish “participation in each substantive and
    jurisdictional element of the underlying offense.” United
    States v. Garrett, 
    720 F.2d 705
    , 713 n.4 (D.C. Cir. 1983). A
    defendant could, for example, aid and abet “travel[ing] in
    foreign commerce[] for the purpose of engaging in any illicit
    sexual conduct with another person,” 
    18 U.S.C. § 2423
    (b),
    without himself crossing any international border. Cf. Raper,
    
    676 F.2d at 850
    .
    Ali’s argument appears to be more nuanced. Ali claims
    the government seeks to use aider and abettor liability to
    expand the extraterritorial scope of the piracy statute beyond
    conduct on the high seas. Because § 1651 expressly targets
    crimes committed on the high seas, he believes Congress
    intended its extraterritorial effect—and, by extension, that of
    the aiding and abetting statute—to extend to international
    waters and no further. And, he claims, our opinion in United
    States v. Yakou supports this proposition by deciding that a
    foreign national who had renounced his legal permanent
    resident status could not be prosecuted for aiding and abetting
    under a statute applicable to “‘[a]ny U.S. person, wherever
    located, and any foreign person located in the United States or
    otherwise subject to the jurisdiction of the United States.’”
    
    428 F.3d at
    243 n.1 (quoting 
    22 C.F.R. § 129.3
    (a)). But this
    language makes clear the intention to limit U.S. criminal
    jurisdiction to certain categories of persons—a restriction
    18
    employing broad aider and abettor liability would have
    frustrated. See 438 F.3d at 252. In other words, Yakou spoke
    to the sort of defendant Congress had in mind, while § 1651’s
    reference to the high seas, in contrast, describes a category of
    conduct.
    Thus, instead of thwarting some clearly expressed
    Congressional purpose, extending aider and abettor liability to
    those who facilitate such conduct furthers the goal of
    deterring piracy on the high seas—even when the facilitator
    stays close to shore. In fact, Yakou distinguished the offense
    at issue there from those crimes—like piracy—in which “the
    evil sought to be averted inherently relates to, and indeed
    requires, persons in certain categories.” Id. In keeping with
    that principle, § 1651’s high seas language refers to the very
    feature of piracy that makes it such a threat: that it exists
    outside the reach of any territorial authority, rendering it both
    notoriously difficult to police and inimical to international
    commerce. See Eugene Kontorovich, Implementing Sosa v.
    Alvarez-Machain: What Piracy Reveals About the Limits of
    the Alien Tort Statute, 80 NOTRE DAME L. REV. 111, 152–53
    (2004). As UNCLOS § 101(c) recognizes, it is self-defeating
    to prosecute those pirates desperate enough to do the dirty
    work but immunize the planners, organizers, and negotiators
    who remain ashore.
    Nor does the Supreme Court’s recent decision in Kiobel
    v. Royal Dutch Petroleum Co., 
    133 S. Ct. 1659
     (2013),
    change the equation. Reiterating that “[w]hen a statute
    provides for some extraterritorial application, the presumption
    against extraterritoriality operates to limit that provision to its
    terms,’” the Court rejected the notion that “because Congress
    surely intended the [Alien Tort Statute] to provide jurisdiction
    for actions against pirates, it necessarily anticipated the statute
    would apply to conduct occurring abroad.” 
    Id.
     at 1667
    19
    (quoting Morrison, 
    130 S. Ct. at 2883
    ). Ali contends that
    § 1651’s high seas requirement is similarly limiting, and that
    the presumption against extraterritoriality remains intact as to
    acts done elsewhere.
    Even assuming Ali’s analogy to Kiobel is valid, 4 he
    overlooks a crucial fact: § 1651’s high seas element is not the
    only evidence of the statute’s extraterritorial reach, for the
    statute references not only “the high seas” but also “the crime
    of piracy as defined by the law of nations.” As explained
    already, the law of nations specifically contemplates, within
    its definition of piracy, facilitative acts undertaken from
    within a nation’s territory. See supra Subsection II.A.1. By
    defining piracy in terms of the law of nations, § 1651
    incorporated this extraterritorial application of the
    international law of piracy and indicates Congress’s intent to
    subject extraterritorial acts like Ali’s to prosecution.
    Why then does § 1651 mention the high seas at all if “the
    law of nations,” which has its own high seas requirements, is
    filling in the statute’s content? Simply put, doing so fits the
    international definition of piracy—a concept that
    encompasses both crimes on the high seas and the acts that
    facilitate them—into the structure of U.S. criminal law. To be
    convicted as a principal under § 1651 alone, one must commit
    piratical acts on the high seas, just as UNCLOS article 101(a)
    4
    Kiobel and its predecessors stated that courts may not infer
    that all applications or provisions in a statute have extraterritorial
    effect just because some do. See, e.g., Morrison, 
    130 S. Ct. at 2883
    ;
    Microsoft Corp. v. AT&T Corp., 
    550 U.S. 437
    , 455–56 (2007).
    These cases do not suggest, as Ali argues, that a statute’s
    application to a particular foreign region cannot rebut the
    presumption against extraterritoriality as to other unspecified
    places.
    20
    demands. But applying aider and abettor liability to the sorts
    of facilitative acts proscribed by UNCLOS article 101(c)
    requires using § 1651 and § 2 in tandem. That is not to say
    § 1651’s high seas requirement plays no role in prosecuting
    Ali for aiding and abetting piracy, for the government must
    prove someone committed piratical acts while on the high
    seas. See Raper, 
    676 F.2d at 849
    . That is an element the
    government must prove at trial, but not one it must show Ali
    perpetrated personally. 5
    Of course, § 1651’s high seas language could also be read
    as Congress’s decision to narrow the scope of the
    international definition of piracy to encompass only those
    actions committed on the high seas. But Ali’s preferred
    interpretation has some problems. Most damningly, to
    understand § 1651 as a circumscription of the law of nations
    would itself run afoul of Charming Betsy, requiring a
    construction in conflict with international law. Ultimately, we
    think it most prudent to read the statute the way it tells us to.
    It is titled “[p]iracy under law of nations,” after all.
    Like the Charming Betsy canon, the presumption against
    extraterritorial effect does not constrain trying Ali for aiding
    and abetting piracy. While the offense he aided and abetted
    must have involved acts of piracy committed on the high seas,
    his own criminal liability is not contingent on his having
    facilitated these acts while in international waters himself.
    B. Conspiracy To Commit Piracy
    5
    The “high seas” reference may also be Congress’s attempt to
    expressly rebut the presumption against extraterritoriality as to
    piracy. See Argentine Republic v. Amerada Hess Shipping Corp.,
    
    488 U.S. 428
    , 440 (1989) (“When it desires to do so, Congress
    knows how to place the high seas within the jurisdictional reach of
    a statute.”).
    21
    Though the aiding and abetting statute reaches Ali’s
    conduct, his conspiracy charge is another matter. In many
    respects conspiracy and aiding and abetting are alike, which
    would suggest the government’s ability to charge Ali with one
    implies the ability to charge him with both. While conspiracy
    is a “separate and distinct” offense in the United States,
    Pinkerton v. United States, 
    328 U.S. 640
    , 643 (1946), it is
    also a theory of liability like aiding and abetting; “[a]s long as
    a substantive offense was done in furtherance of the
    conspiracy, and was reasonably foreseeable as a necessary or
    natural consequence of the unlawful agreement, then a
    conspirator will be held vicariously liable for the offense
    committed by his or her co-conspirators.” United States v.
    Moore, 
    651 F.3d 30
    , 80 (D.C. Cir. 2011) (per curiam)
    (internal quotation marks omitted).
    Yet a crucial difference separates the two theories of
    liability. Because § 371, like § 2, fails to offer concrete
    evidence of its application abroad, we turn, pursuant to the
    Charming Betsy canon, to international law to help us resolve
    this ambiguity of meaning. Whereas UNCLOS, by including
    facilitative acts within article 101’s definition of piracy,
    endorses aider and abettor liability for pirates, the convention
    is silent on conspiratorial liability. International law provides
    for limited instances in which nations may prosecute the
    crimes of foreign nationals committed abroad, and, in
    invoking universal jurisdiction here, the government
    predicates its prosecution of Ali on one of those theories. And
    although neither side disputes the applicability of universal
    jurisdiction to piracy as defined by the law of nations,
    UNCLOS’s plain language does not include conspiracy to
    commit piracy. See, e.g., Ved P. Nanda, Maritime Piracy:
    How Can International Law and Policy Address This
    Growing Global Menace?, 39 DENV. J. INT’L L. & POL’Y 177,
    22
    181 (2011) (“It should be noted that the [UNCLOS] definition
    does not refer to either an attempt to commit an act of piracy
    or to conspiracy relating to such an act, but it does include
    voluntary participation or facilitation.”). The government
    offers us no reason to believe otherwise, and at any rate, we
    are mindful that “imposing liability on the basis of a violation
    of ‘international law’ or the ‘law of nations’ or the ‘law of
    war’ generally must be based on norms firmly grounded in
    international law.” Hamdan v. United States, 
    696 F.3d 1238
    ,
    1250 n.10 (D.C. Cir. 2012) (emphasis added). International
    law does not permit the government’s abortive use of
    universal jurisdiction to charge Ali with conspiracy. Thus, the
    Charming Betsy doctrine, which was no impediment to Ali’s
    aider and abettor liability, cautions against his prosecution for
    conspiracy.
    The government hopes nonetheless to salvage its
    argument through appeal to § 371’s text. Though courts
    construe statutes, when possible, to accord with international
    law, Congress has full license to enact laws that supersede it.
    See Yunis, 
    924 F.2d at 1091
    . The government suggests
    Congress intended to do precisely that in § 371, which
    provides that “[i]f two or more persons conspire . . . to
    commit any offense against the United States . . . and one or
    more of such persons do any act to effect the object of the
    conspiracy,” each is subject to criminal liability. Homing in
    on the phrase “any offense against the United States,” the
    government contends Congress intended the statute to apply
    to all federal criminal statutes, even when the result conflicts
    with international law. Yet, as we explained above, if we are
    to interpret § 371 as supplanting international law, we need
    stronger evidence than this. Indeed, the Supreme Court
    recently rejected the notion that similar language of general
    application successfully rebuts the presumption against
    extraterritorial effect. See Kiobel, 
    133 S. Ct. at 1665
     (“Nor
    23
    does the fact that the text reaches ‘any civil action’ suggest
    application to torts committed abroad; it is well established
    that generic terms like ‘any’ or ‘every’ do not rebut the
    presumption against extraterritoriality.”).
    Under international law, prosecuting Ali for conspiracy
    to commit privacy would require the United States to have
    universal jurisdiction over his offense. And such jurisdiction
    would only exist if the underlying charge actually falls within
    UNCLOS’s definition of piracy. Because conspiracy, unlike
    aiding and abetting, is not part of that definition, and because
    § 371 falls short of expressly rejecting international law,
    Charming Betsy precludes Ali’s prosecution for conspiracy to
    commit piracy. The district court properly dismissed Count
    One.
    III. THE HOSTAGE TAKING CHARGES
    The linguistic impediments that trouble Counts One and
    Two do not beset the charges for hostage taking under 
    18 U.S.C. § 1203
    . The statute’s extraterritorial scope is as clear
    as can be, prescribing punishments against “whoever, whether
    inside or outside the United States, seizes or detains and
    threatens to kill, to injure, or to continue to detain another
    person in order to compel a third person or a governmental
    organization to do or abstain from doing any act.” 
    18 U.S.C. § 1203
    (a). We also need not worry about Charming Betsy’s
    implications, as § 1203 unambiguously criminalizes Ali’s
    conduct. Section 1203 likely reflects international law
    anyway, as it fulfills U.S. treaty obligations under the widely
    supported International Convention Against the Taking of
    Hostages, Dec. 17, 1979, 18 I.L.M. 1456, 1316 U.N.T.S. 205.
    See United States v. Lin, 
    101 F.3d 760
    , 766 (D.C. Cir. 1996).
    Nor, as in the case of the federal piracy statute, is there any
    uncertainty as to the availability of conspiratorial liability,
    24
    since the statute applies equally to any person who “attempts
    or conspires to” commit hostage taking. 
    18 U.S.C. § 1203
    (a).
    Faced with this reality, Ali has adopted a different
    strategy when it comes to Counts Three and Four, swapping
    his statutory arguments for constitutional ones. He relies on
    the principle embraced by many courts that the Fifth
    Amendment’s guarantee of due process may impose limits on
    a criminal law’s extraterritorial application even when
    interpretive canons do not. Though this Circuit has yet to
    speak definitively, see United States v. Delgado-Garcia, 
    374 F.3d 1337
    , 1341–43 (D.C. Cir. 2004) (explaining that, even if
    prosecuting the appellants for their extraterritorial conduct
    would deprive them of due process, the argument had been
    waived through their unconditional guilty pleas), several other
    circuits have reasoned that before a federal criminal statute is
    given extraterritorial effect, due process requires “a sufficient
    nexus between the defendant and the United States, so that
    such application would not be arbitrary or fundamentally
    unfair.” United States v. Davis, 
    905 F.2d 245
    , 248–49 (9th
    Cir. 1990) (internal citation omitted); see United States v.
    Brehm, 
    691 F.3d 547
    , 552 (4th Cir. 2012); United States v.
    Ibarguen-Mosquera, 
    634 F.3d 1370
    , 1378–79 (11th Cir.
    2011); United States v. Yousef, 
    327 F.3d 56
    , 111–12 (2d Cir.
    2003) (per curiam); United States v. Cardales, 
    168 F.3d 548
    ,
    552–53 (1st Cir. 1999). 6 Others have approached the due
    6
    Some courts have suggested grouping these decisions into
    two categories: those that “look for real effects or consequences
    accruing in the United States before they find [a] nexus” and those
    that “require only that extraterritorial prosecution be neither
    arbitrary nor fundamentally unfair, and are not concerned with
    whether a sufficient nexus exists.” United States v. Campbell, 
    798 F. Supp. 2d 293
    , 306–07 (D.D.C. 2011). The distinction may be
    illusory, with the “nexus” inquiry serving more as a proxy for
    whether a particular prosecution is unfair. See 
    id. at 307
    . For
    25
    process issue in more cautious terms. See United States v.
    Suerte, 
    291 F.3d 366
    , 375 (5th Cir. 2002) (assuming, without
    deciding, the Due Process Clause constrains extraterritorial
    reach in order to conclude no violation occurred); United
    States v. Martinez-Hidalgo, 
    993 F.2d 1052
    , 1056 (3d Cir.
    1993) (accord). Likewise, the principle is not without its
    scholarly critics. See, e.g., Curtis A. Bradley, Universal
    Jurisdiction and U.S. Law, 2001 U. CHI. LEGAL F. 323, 338
    (“[I]t may be logically awkward for a defendant to rely on
    what could be characterized as an extraterritorial application
    of the U.S. Constitution in an effort to block the
    extraterritorial application of U.S. law.”). We need not decide,
    however, whether the Constitution limits the extraterritorial
    exercise of federal criminal jurisdiction. Either way, Ali’s
    prosecution under § 1203 safely satisfies the requirements
    erected by the Fifth Amendment. 7
    A. Due Process and Extraterritorial Conduct
    In support of his due process argument, Ali cites a
    panoply of cases concerning personal jurisdiction in the
    context of civil suits. It is true courts have periodically
    borrowed the language of personal jurisdiction in discussing
    the due process constraints on extraterritoriality. But Ali’s
    flawed analogies do not establish actual standards for judicial
    present purposes, that question is purely academic, as Ali does not
    tether his argument to a particular version of the due process
    argument.
    7
    Ali has not cited—and we have not found—any case in
    which extraterritorial application of a federal criminal statute was
    actually deemed a due process violation. Although that does not
    mean such a result is beyond the realm of possibility, it does
    suggest Ali’s burden is a heavy one, for he traverses uncharted
    territory.
    26
    inquiry; the law of personal jurisdiction is simply inapposite.
    See United States v. Perez Oviedo, 
    281 F.3d 400
    , 403 (3d Cir.
    2002). To the extent the nexus requirement serves as a proxy
    for due process, it addresses the broader concern of ensuring
    that “a United States court will assert jurisdiction only over a
    defendant who should reasonably anticipate being haled into
    court in this country.” United States v. Klimavicius-Viloria,
    
    144 F.3d 1249
    , 1257 (9th Cir. 1998) (internal quotation marks
    omitted). What appears to be the animating principle
    governing the due process limits of extraterritorial jurisdiction
    is the idea that “no man shall be held criminally responsible
    for conduct which he could not reasonably understand to be
    proscribed.” Bouie v. City of Columbia, 
    378 U.S. 347
    , 351
    (1964) (internal quotation marks omitted). The “ultimate
    question” is whether “application of the statute to the
    defendant [would] be arbitrary or fundamentally unfair.”
    United States v. Juda, 
    46 F.3d 961
    , 967 (9th Cir. 1995).
    United States v. Shi, 
    525 F.3d 709
     (9th Cir. 2008), is
    most on point. Shi dealt with a due process challenge to the
    defendant’s prosecution under 
    18 U.S.C. § 2280
    , which
    implements the Convention for the Suppression of Unlawful
    Acts Against the Safety of Maritime Navigation, Mar. 10,
    1988, 27 I.L.M. 672, 1678 U.N.T.S. 222. See 
    525 F.3d at
    717–24. Because “the Maritime Safety Convention . . .
    expressly provides foreign offenders with notice that their
    conduct will be prosecuted by any state signatory,” due
    process required no specific nexus between the defendant and
    the United States. 
    Id. at 723
    . In other words, the treaty at issue
    in Shi did what the International Convention Against the
    Taking of Hostages does here: provide global notice that
    certain generally condemned acts are subject to prosecution
    27
    by any party to the treaty. 8 We agree with the Ninth Circuit
    that the Due Process Clause demands no more.
    That Ali’s Counts Three and Four concern hostage taking
    and not piracy in the technical sense does nothing to alter
    Shi’s logic. The Ninth Circuit did reason that “the acts with
    which Shi is charged constitute acts of piracy” and
    “[p]rosecuting piracy was the original rationale for creating
    universal jurisdiction.” 
    Id.
     Yet strictly speaking, Shi was not
    charged with piracy but with the separate, albeit analogous,
    offense of violence against maritime navigation. See 
    18 U.S.C. § 2280
    . And it is the “universal condemnation of the
    offender’s conduct,” not some theory of universal jurisdiction,
    that drove the Ninth Circuit’s reasoning. 
    525 F.3d at 723
    .
    That is why the court also cited Martinez-Hidalgo, which
    dealt with narcotics trafficking, see 
    993 F.2d at
    1056—an
    offense not generally understood to be subject to universal
    jurisdiction, see RESTATEMENT (THIRD) OF FOREIGN
    RELATIONS LAW § 404. By that standard, hostage taking is
    also an offense whose proscription “is a result of universal
    condemnation of those activities and general interest in
    cooperating to suppress them, as reflected in widely-accepted
    8
    Interestingly, Shi even offers some insight into our own
    Circuit’s precedent. Citing our opinion in United States v. Rezaq,
    
    134 F.3d 1121
     (D.C. Cir. 1998), the Ninth Circuit found
    particularly relevant our decision to apply an aircraft hijacking
    statute to the defendant “without noting any possible due process
    concerns.” 
    525 F.3d at 724
    . Acknowledging that our silence “may
    have stemmed from any number of reasons,” the court found it
    “important to note that, like § 2280, the statute in Rezaq was
    enacted to implement an international agreement to extradite and to
    prosecute perpetrators of widely-condemned conduct.” Id. Rezaq is
    not squarely analogous, however, since “hijacking of aircraft,” like
    piracy, is a universal jurisdiction offense. See 
    134 F.3d at 1131
    ;
    RESTATEMENT (THIRD) OF FOREIGN RELATIONS LAW § 404.
    28
    international agreements and resolutions of international
    organizations.” Id. § 404 cmt. a. Regardless, Shi’s comparison
    of § 2280 to piracy was an alternate holding, not a necessary
    premise to its conclusion that a treaty may provide notice
    sufficient to satisfy due process—a fact even Ali concedes.
    See Appellee Br. 37.
    Ali also complains that though China was a signatory to
    the relevant international agreement in Shi, Somalia is not a
    party to the International Convention Against the Taking of
    Hostages, 9 meaning his home nation has not consented to
    U.S. criminal jurisdiction over its hostage-taking nationals.
    True, as a matter of international law, this case may not be so
    obvious as those in which “the flag nation has consented to
    the application of United States law to the defendants.”
    United States v. Angulo-Hernández, 
    565 F.3d 2
    , 11 (1st Cir.
    2009). But Ali mistakes the due process inquiry for the
    customary international law of jurisdiction. “Whatever merit
    [these] claims may have as a matter of international law, they
    cannot prevail before this court. . . . Our duty is to enforce the
    Constitution, laws, and treaties of the United States, not to
    conform the law of the land to norms of customary
    international law.” Yunis, 
    924 F.2d at 1091
    . Whatever due
    process requires here, the Hostage Taking Convention
    suffices by “expressly provid[ing] foreign offenders with
    notice that their conduct will be prosecuted by any state
    signatory.” Shi, 
    525 F.3d at 723
    . That is what Shi said. It did
    not hold that due process depends on the participation of the
    defendant’s nation in the agreement.
    9
    Somalia does not join most other nations in this regard. As of
    May 28, 2013, the treaty has 39 signatories and 170 parties. See
    United Nations Treaty Collection, International Convention Against
    the        Taking        of      Hostages,         available        at
    http://treaties.un.org/Pages/ViewDetails.aspx?mtdsg_no=XVIII-
    5&chapter=18&lang=en.
    29
    Finally, Ali asserts that “[f]or non-citizens acting entirely
    abroad, a jurisdictional nexus exists when the aim of that
    activity is to cause harm inside the United States or to U.S.
    citizens or interests.” United States v. Al Kassar, 
    660 F.3d 108
    , 118 (2d Cir. 2011). In Al Kassar, these interests were
    present because “[t]he defendants’ conspiracy was to sell
    arms to FARC with the understanding that they would be used
    to kill Americans and destroy U.S. property.” 
    Id.
     There is
    good reason to believe that whatever “nexus” due process
    might demand is not “jurisdictional” in the proper sense of the
    term. See Delgado-Garcia, 
    374 F.3d at 1343
     (“Appellants’ . .
    . . assertion is a claim that the due process clause limits the
    substantive reach of the conduct elements of 
    8 U.S.C. § 1324
    (a), not a claim that the court lacks the power to bring
    them to court at all.”). But even assuming Al Kassar’s
    characterization is right, the decision only tells us when such
    2013) (“‘P ⊃ Q’ does not mean ‘¬P ⊃ ¬Q.’”). And in any
    a nexus exists, not when it is absent. See New England Power
    Generators Ass’n v. FERC, 
    707 F.3d 364
    , 370 n.3 (D.C. Cir.
    event, this quote from Al Kassar cannot sustain the expansive
    construction Ali accords it. Otherwise, the Fifth Amendment
    would preclude prosecution even of universal jurisdiction
    offenses like piracy.
    Al Kassar also states, “Fair warning does not require that
    the defendants understand that they could be subject to
    criminal prosecution in the United States so long as they
    would reasonably understand that their conduct was criminal
    and would subject them to prosecution somewhere.” 
    660 F.3d at 119
    . Other courts have made similar statements. See, e.g.,
    Martinez-Hidalgo, 
    993 F.2d at 1056
     (“Inasmuch as the
    trafficking of narcotics is condemned universally by law-
    abiding nations, we see no reason to conclude that it is
    ‘fundamentally unfair’ for Congress to provide for the
    30
    punishment of persons apprehended with narcotics on the
    high seas.”). While Ali protests that the Second Circuit cannot
    have meant what it said, the consequence of a literal reading
    is not the limitless prosecutorial power he envisions. Given
    presumptions like the Charming Betsy and extraterritoriality
    canons, conduct abroad would only be subject to statutes with
    clear foreign scope (like § 1203). In fact, since it is those
    canons and not the Fifth Amendment that have thus far
    restrained such prosecutorial abuse, Ali’s claim that the
    government’s position somehow vitiates essential protections
    seems dubious.
    Lastly, we mention that the district court initially denied
    dismissal of Counts Three and Four. See Ali II, 885 F. Supp.
    2d at 45 (“Because the hostage taking charges allege the same
    high-seas conduct for which Ali is lawfully subject to
    prosecution for piracy, and in light of the notice that the
    Hostage Taking Convention provides, the Court concludes
    that there is nothing fundamentally unfair about Ali's
    prosecution under § 1203.”). It was only once the district
    court doubted the government’s ability to prove either piracy
    count that it decided haling Ali into a U.S. court to answer
    charges of hostage taking would violate due process. See Ali
    III, 885 F. Supp. 2d at 61–62. Since we have reversed the
    district court’s decision narrowing the scope of Count Two,
    the logic of Ali II, which allowed Ali’s charges for hostage
    taking to proceed, is once again applicable.
    B. Miscellaneous Due Process Arguments
    For his final salvo, Ali fires a barrage of “Special
    Criminal Law Concerns” he claims are relevant to his right to
    due process. We respond in kind:
    31
    •   Ali laments the “lack of vicinage” between his alleged
    crime and the legal forum set for his prosecution. See
    United States v. Cores, 
    356 U.S. 405
    , 407 (1958) (“The
    provision for trial in the vicinity of the crime is a
    safeguard against the unfairness and hardship involved
    when an accused is prosecuted in a remote place.”). But
    Counts Three and Four introduce no unique detriment to
    Ali’s defense beyond that already inherent to his piracy
    prosecution. And the sweep of Ali’s argument is
    overinclusive, as it would seemingly defeat all
    extraterritorial applications of criminal statutes.
    •   Ali next targets the length of his pretrial detention. While
    he is correct that excessive pretrial detention may in
    certain circumstances deprive a defendant of his right to a
    speedy trial, “courts must still engage in a difficult and
    sensitive balancing process.” Barker v. Wingo, 
    407 U.S. 514
    , 533 (1972). Beyond stating the length of his
    detention, Ali has offered no specifics on how his rights
    have been violated or his defense prejudiced.
    •   Invoking double jeopardy norms, Ali contends his
    susceptibility to future prosecution in, say, Denmark or
    Somalia renders inappropriate his prosecution in the
    United States. Though he acknowledges the Fifth
    Amendment’s prohibition on double jeopardy does not
    constrain prosecutions by separate sovereigns, see United
    States v. Rashed, 
    234 F.3d 1280
    , 1282 (D.C. Cir. 2000),
    he nonetheless tries to smuggle in the underlying principle
    via the Due Process Clause. To invoke the principle of
    double jeopardy in order to thwart a well-recognized
    exception to the Double Jeopardy Clause is already
    strange. Yet even more mystifying is his attempt to make
    the point in the first forum to subject him to criminal
    charges. It seems such an argument would be more
    32
    compelling in the next forum (if any) that opts to
    prosecute him.
    Along with these due process concerns, Ali discusses
    principles of international comity. The issue, as well as its
    import for due process, is addressed in cursory fashion. No
    matter. An amorphous reference to international comity is no
    basis for gainsaying the clearly expressed intention of the
    United States, by both treaty and statute, to prosecute hostage
    takers for their offenses abroad.
    IV. CONCLUSION
    We affirm the district court’s dismissal of Count One.
    We reverse the district court’s narrowing of the scope of
    Count Two to acts Ali performed while on the high seas and
    reverse dismissal of Counts Three and Four.
    So ordered.
